Foreword For the majority of our projects we have been using pretty much the same PCB manufacturer called Itead Studio. They have always been the front runners offering good quality at exceptionally low prices. For all our projects the quality has always been ‘good enough’ until the moment when we began making Olinuxino and noticed […] This is a second spin of Luminardo boards with the focus on elimination minor mistakes found in the revision 1.0. A motion sensor is fully integrated with the PCB this is why the board has an inflow on top of its outline. Also an obsolete inductor is replaced with the one of a similar footprint […] This is a deep redesign of MVFD 16S8D Panel Rev.1.0 project which fixes minor and major issues and finally solves the fundamental problem of some parts becoming obsolete. Let’s reiterate the reasons which were the main driving forces of the project to come into existence: – Single power source (+5V) which makes it possible to […] Pilot Display Rev.1.0 PCBs finally arrived. At a first glance nothing is terribly wrong, everything seems to be fine which is a good start. However, there is always something in rev1.0 boards or schematics so will see what the subsequent assembling process and preliminary test bring us. As always, Itead Studio PCB manufacturing service has […] Just recently by a pure accident we became involved into very unusual project. Willing to become known to some degree amongst the local Sydney electronics enthusiasts we decided to take part in one of the community projects and help to build something. It didn’t take much time to wait for someone who posted a request […] Building a 3D model from PCB design files can bring your project to a totally new level. It comes at a price as it requires extra design time but being properly done it saves a lot of effort and money in the future as it minimises risks by helping to capture issues on early stages […] The GSM part is based on SIM900D GSM module. SIM300DZ has the same pin layout and designation so it might be used as a replacement of SIM900D. Q1 transistor, R2, R3 and R4 resistors are used to drive LED1 ‘NET LIGHT’ which indicates module networking status. CONN4 is a SMT antenna connector. Q2 transistor and […] The heart of the unit is CPU ATMega1280 microprocessor running at 14.7456 MHz (Y3 crystal). This frequency provides required accuracy to clock serial communications at 57600/115200 bps between the unit and external devices such as PC, GPS module, GPRS modem, JPEG cameras etc. The ATMega1280 processor has four hardware serial ports facilitating simultaneous interactions with […] |
